Descripción general

Cholecalciferol acts as a hormone precursor since it requires two stages of metabolism: first to 25-hydroxycholecalciferol; then to 1α, 25-dihydroxycholecalciferol. One unit (U.S.P. or international) is defined as the activity of 0.025 μg of vitamin D3 contained in the USP vitamin D reference standard.
Cholecalciferol is sourced either through the diet or exposing skin to ultraviolet rays. Oral administration of vitamin D3 is readily absorbed and is stored in adipose tissue.

Acciones bioquímicas o fisiológicas

Deficiency of vitamin D is often observed in chronic kidney disease.
Vitamin D acts through a receptor that is a member of the ligand-dependent transcription factor superfamily. Modulates the proliferation and differentiation of both normal and cancer cells. Has antiproliferative and antimetastatic effects on breast, colon, and prostate cancer cells. Activated vitamin D receptors in intestine and bone maintain calcium absorbance and homeostasis.

Almacenamiento y estabilidad

Cholecalciferol C9756 is packaged under argon gas. If it is stored unopened at 2-8°C and protected from light, this product should be stable for a minimum of three years. Unused portions should be stored under nitrogen or argon gas. Deterioration is negligible after storage of one year in amber-evaculated ampules at refrigerator temperatures. It is oxidized and inactivated by moist air within a few days.
